MANGLE-APRON GUIDE.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed August 28, 1907. Serial No. 390,437.

T 0 all whom it may concern:

Be it known that I, ELDIE P. Wool), a citizen of the United States,residing at Los Angeles, county of Los Angeles, and State of California,have invented a new and useful Improvement in Mangle-Apron Guides, ofwhich the following is a specification.

My invention relates to an apron guide adapted for use on a laundrymangle provided with an apron adjusting roller and the object thereof isto provide an automatic device which will keep the apron in the centerof the cylinders without any attention on the part of the operatorsusing the mangle.

A further object is to provide a' device which in no way interferes withthe usual operation of the mangle and which does not injure the apron byits action thereon.

A further object is to provide a device in sim le and economical form sothat it is not liab e to become disordered and fail to perform its duty.

I accomplish these objects by means of the device described herein andillustrated in the accompanying drawings in which Figure 1,is asectional elevation of a mangle to which my guide may be attached. Fig.2,is a detailed perspective view of parts of the mangle with myautomatic guide operatively mounted thereon. Fig. 3,is an enlargedsectional view of the friction reel mounted on the cylinder shaft. Fig.4,is a viefv similar to Fig. 3 of a modified form of ree In the drawings5 designates a laundry mangle of approved construction provided withcylinders 6 and aprons 7, the passage of which through the machine isshown in dotted lines. One of the aprons 7 passes over cylinder 8 at thedischarge end of the mangle and the other passes over a similar cylinder9. The apron which passes over cylinder 8 is adjusted and guided bymeans of a movable cylinder 10 which in usual practice is adjusted bymeans of a foot lever, (not shown). The apron which passes over cylinder9 is similarly adjusted by a cylinder 11 over which it passes. As bothof these adjusting cylinders are operated in precisely the same manneran illustration and description of one of the same will suffice forboth.

In Fig. 2 cylinders 8 and 10 are illustrated with their operating partsand the same will be described, the illustration and description forcylinders 9 and 11 being exactly similar with the exception that theyare further re- 4 be operated by a pivoted lever 16.

moved from each other. Adjusting cylinder 10 is mounted in bearings 12which are mounted on pivoted arms 13 which pivoted arms are movable bymeans of levers 14. Levers 14 are pivotally connected between theirouter ends by a shift bar 15 adapted to Whenever shift bar 15 is movedlongitudinally it will be manifest that the ends of cylinder 10 will bemoved transversely and in opposite directions. Thus if shift bar 15 ismoved to the right in the drawing the right hand end of cylinder 10 willbe moved forwardly while the left hand end will be moved rearwardly.From Figs. 1 and 2 it will be noted that apron 7 makes a considerableangle in passing over cylinder 10 so that if one end of cylinder 10 ismoved forwardly apron 7 will tend to run squarely off of the cylinderand will consequently slowly run over to the other side of cylinder 8.My device is designed to keep the apron in a central position on thecylinder by automatically moving the adjusting cylinder to run the apronto the side from which it has first moved. In accomplishing this end Iplace on each end of shaft 17, on which cylinder 8 is mounted, andadjacent the ends of cylinder 8, a friction reel 18 which may bepreferably constructed in either of two forms which are shown in Figs. 3and 4.

In the form shown in Fig. 3 a sleeve 20 is loosely mounted on shaft 17and carries on its outer end a spool 21 on which chain 22 is adapted tobe wound. On its inner end sleeve 20 is provided with a cone pulley 23whose inner face is placed close against the end of cylinder 8. Pulley23 is provided with an internal conical friction clutch 24 against whichthe pulley is pressed by coiled spring 25 whose pressure is renderedadjustable by means of nut 26 in screw threaded engagement with sleeve20. When apron 7 runs over to one side of the machine and its edge runsonto pulley 23 chain 22 is wound up on spool 21 and the outer end oflever 16, to which the chains are attached, is pulled toward the side towhich the apron has run. This action results in moving forwardly the endof the adjusting roller on that side to which the apron has run so thatthe apron will run over to the other side of the machine. If the apronshould run on pulley 23 longer than is necessary to move cylinder 10 tothe fullest extent pulley 23 will slide on friction clutch 24 until theapron again moves to the other side of the cylinder.

In'Fig. 4 I have shown a modified form in which pulley 23 is directlysecured to sleeve.

' friction clutch form gives better results in use with a new apronwhere the edges are very tight against the cylinders. Both ul leys aremade slightly cone shaped so t at the edge of the apron will run up ontothe same easily.

From the foregoing descri tion it will be observed that my device wilguide a mangle apron in a central position upon the cylin ders of themangle, keeping the same automatically in that position without anyattention on the part of the operators using the machine. justingrollers are not moved to their limiting positions as the aprons movefrom one side to the other very slowly and a very slight movement of theadjusting rollers suffioes to keep the same in a central position.

Having described my invention what I claim as new and desire to secureby Letters Patent is 1. An apron guide adapted to operate with a mangleaving an apron adjusting cylinder, comprising a conical pulley mountedon each end of a cylinder over which the apron passes, each of saidpulleys adapted to receive the apron on its periphery, and said pulleysbeing operatively connected to the adjusting cylinder.

2. In an apron guide adapted to operate In practical operation the ad inconnection with a mangle having an apron adjusting roller thereon, apulley loosely mounted on each end of the mangle cylinder over whichsaid apron passes, said pulleys being of approximately the same diameteras the cylinder and operatively connected to said adjusting-cylinder.

3. An a ron guide adapted to operate with a mangle having an apronadjusting cylinder, comprising a conical pulley loosely mounted on acylinder shaft at each end of a cylinder over which the apron passes,said pulleys being of approximately the same diameter as the cylinderand being operatively connected to said adjusting roller.

4. In an apron guide adapted to operate on a mangle having an apronadjusting cylinder thereon, a spool loosely mounted on a cylinder shaftof the mangle over which cylinder the apron passes, a pulleyfrictionally connected with each of said spools, said pulleys adapted tobe rotated by said apron, and connective means between said spools andsaid adjusting cylinder whereby upon the rotation of one of said spoolsthe axis of the I adjusting cylinder is moved.

5. In a device of the class described, a revoluble cylinder, an apronadjusting roller, an

apron passing over said cylinder and said roller, a pulley ofapproximately the same diameter as said cylinder rotatively mounted oneach end of said cylinder, and connecting means between said pulleys andsaid adjusting roller.

In witness that I claim the foregoing I have hereunto subscribed my namethis 21 day of August, 1907.
